PAPER-COP TUBES.

Specification of Letters Patent No. 17,746, dated July '7, 1857.

To all whom it may concern.'

Be it known that I, ALEXANDER Mc- CAUsLAND, of Providence, in the countyof Providence and State of Rhode Island, have invented a new andimproved mode for the construction of the machines known as Papercop-tubes, used on mule-spindles in cotton-spinning and u on s indlesshaped like mule-spindles, and do ereby declare that the following is afull, clear, and exact description of the construction and operation ofthe same.

The mode of construction of my tube is as follows: Cut a strip of paperinto the shape of the drawing hereto annexed (marked A), and which ishereby made a part of this specification, the same varying 1n length ast e size of the tubes may require, and having one of its edges outstraight and the other edge cut straight for about two (2) inches fromthe base or large end of the strip, and being from that point cut taeringly until it comes to a point at the ot er end of the strip with theopposite straight edge. The length of the stri may vary from ten (10) totwelve (12) inc es, more or less, according to the required size of thetube to be constructed. The tube may be made from any kind of paper asmay be desired, although brown Manila paper is the kind most generallyused. In order to complete the construction of the tubes as improved byme, the strip of paper is to be moistened with aste at one or its sides,then the base or iOarger end ofthe strip is wound first by hand onceround a spindle and the spindle is then carefully turned until the wholeis wound up, 4the winding being made tight enough to cause the papers toadhere through its whole extent.

By this process the tube is produced shaped in the form of a truncatedcone, and being about six (6) times more or less thicker at the base orlarger end than at the top; and the bore remains the same sizethroughout.

The mode ofthe practical operation of this tube upon spindles isrecisely similar to that of the old form of tile paper cop tubes, uponwhich they are an improvement.

The improvement which results from my invention in the working of thesetubes is as follows: Whereas in the course of the working of the oldtubes it is customary to use them as long as they will last, and owingto their construction they are not calculated -for endurance, because asthe tubes are the same size at both ends, and thinly made, they arealways split by being used a few times on the mule or shuttle spindle,and in using the tubes afterward the split or torn parts prevent theyarn from running off freely on account of the adhesion of the thread oryarn, as the case may be, to the split or torn portions of the tube,consequently both tube and yarn are thrown away as waste.

Now, by my improvement it is effected that, owing to the increasedthickness ofthe `base or lar er end of the tube, which is first put upont e spindle, from necessity, on account of the tapering shape of thetube, it is impossible to split them by ordinary use; and, owing to thetapering shape of the tube, as described above, the yarn will in allcases run o it much more easily than it does off of the original ones,thereby saving immense waste, both in the amount of yarn and thread nowthrown away and in the number of tubes themselves now necessarily used.

What I claim as my invention, and desire to secure by Letters Patent,is-

The paper cop tube made of a'strip of paper of the form represented inthe diagram A in the manner described, whereby greater strength is givento the base of the tube, while the desired conical form is at the sametime attained.
